BACKGROUND/OBJECTIVES: This study aims to explore the potential of convenience stores as platforms for healthy food consumption, including low-sodium options, in response to the increasing trend of meal behaviors at convenience stores and the growing demand for healthy eating. SUBJECTS/METHODS: In the study, 627 Korean participants aged 10 to 39 were involved. A self-reported questionnaire survey was used and questions were regarding purchase patterns, consumption behaviors, perceptions and selection attributes of convenience store foods, and consumer perception factors for low-sodium options. Data analysis was conducted using SPSS 26.0 (SPSS, Version 26.0 for Windows, SPSS Inc., Chicago, IL, USA). RESULTS: The study uncovered significant disparities in the consumption behavior and perception of convenience store foods, as well as variations in the importance and satisfaction levels with convenience store food attributes, including consumer perception factors for low-sodium options, based on sex and age. Furthermore, it was observed that awareness of the need for low-sodium options significantly influenced purchase intentions. CONCLUSION: This study analyzed consumer attitude toward low-sodium convenience store foods to assess the potentiality for promoting healthy eating in convenience stores. These findings indicate the important role that convenience stores can play as platforms for healthy food sales.

Metabolic syndrome is a cluster of metabolic risk factors associated with increased risk of cardiovascular diseases. Recently, the prevalence of metabolic syndrome has increased in Korea. The aim of this study was to develop a Healthy Han-sik Nutrition Education Program (HHNEP) based on commonly recognized Korean foods in order to decrease metabolic syndrome risks. The target population of the HHNEP is adults with metabolic risk factors. The initial version of the HHNEP was developed based on a review of literature and various dietary guidelines by expert committees as well as the results of a survey on the perception of common Korean dishes and foods as Han-sik. The focus group discussion conducted of nine participants from the target population. After minor modification, the final version was developed. The contents included five sections: 1) aims, 2) introduction of Korean Food Guidance System, 3) cholesterol contents in food, 4) menu planning method using Han-sik, and 5) examples of daily Han-sik menu. The Han-sik list was selected based on the results from a Han-sik perception answered by 35 Korean adults aged 30-60 years using 517 frequently consumed Korean foods from the fourth Korea National Health and Nutrition Examination Survey. The nutrition education program was developed based on scientific evidence for the prevention of metabolic syndrome and focuses on tailoring education to an individual's dietary problems. Educational method was developed by a group of expert committees based in planned behavior theory and related research results. The education method consisted of assessment of current diet, four face-to-face nutrition education sessions over 8 weeks, and evaluation after 8 and 16 weeks. Initial version of nutrition education materials and methods was tested for feasibility by a select group of nine Korean healthy adults. Successful implementation of the program would include application by nutritional professionals at the health promotion center of the hospitals, public health center, and work sites. Intervention studies are needed to evaluate the feasibility and effectiveness of this program before large-scale applications.

Dietary counseling is undoubtedly important for prevention and treatment of chronic diseases. Several dietary counseling methods have been developed and used in Japan to promote healthier diets. However, in Japan, few studies have established effective counseling methods. We developed a computer-assisted tailored dietary counseling system with self-administered diet history questionnaire (DHQ) to assess nutrient intakes and the feedbacks for counseling. We examined the effectiveness of the system in three studies , two among mildly-hypercholesterolemic and one among healthy subjects. We observed significant changes in intakes of targeted nutrients in all three studies. We also observed favorable changes in the corresponding serum and urinary biomarkers in two studies, i.e., non-significant change in serum cholesterol, serum carotene and vitamin C, and a significant change in 24-hour urinary excretion of sodium. In addition, one of the studies observed a significant modified dietary habit for one-year after the intervention was completed. No unfavorable change was observed for non-targeted nutrients in all three studies. The dietary counseling system with DHQ was concluded to be effective among motivated high-risk and healthy subjects. The system's application to other diseases and populations such as children, adolescents, and elderly, should be examined further. (J Community Nutrition 5(2) : 112-119, 2003)

BACKGROUND/OBJECTIVES: The dietary intake of foods with fermentable oligosaccharides, disaccharides, monosaccharides, and polyols (FODMAP) is known to adversely affect patients with irritable bowel syndrome (IBS). However, the effects of FODMAP have been studied predominantly among Western populations. This study aimed to identify foods high in FODMAP content which form a part of the Korean adult diet and obtain basic data for the preparation of IBS guidelines. SUBJECTS/METHODS: An online survey of 1,000 adults from the general population in the age group of 20 to 40 years was performed. Data from 787 participants (men, 386; women, 401) were analyzed. The general characteristics of the participants, health status, IBS diagnosis using the Rome III diagnostic criteria, semi-quantitative food frequency questionnaire findings, and food items causing symptoms were analyzed. RESULTS: Overall, 169 participants (21.5%) had IBS. The contribution of the FODMAP nutrients in both IBS and healthy groups was as follows: fructan > lactose > excess fructose > sorbitol > mannitol > galacto-oligosaccharides (GOS). The fructan intake was 4.6 ± 2.2 g/day and 4.3 ± 2.5 g/day in the IBS and healthy groups (P = 0.014), respectively. In the IBS group, the ratio of the intake of fructan to the total FODMAP intake was 39.5%, 29.8%, and 5.8% through onions, garlic, and bananas, respectively. CONCLUSIONS: Fructan was the FODMAP nutrient most consumed by Korean adults. Therefore, given the difference in the dietary habits of each country's population, the dietary guidelines for IBS should be country specific.

BACKGROUND/OBJECTIVES: Recently, there has been an increased interest in the importance of family meals on children's health and nutrition. This study aims to examine if the eating habits and eating behaviors of children are different according to the frequency of family dinners. SUBJECTS/METHODS: The subjects were third-grade students from 70 elementary schools in 17 cities nationwide. A two-stage stratified cluster sampling was employed. The survey questionnaire was composed of items that examined the general characteristics, family meals, eating habits, eating behaviors, and environmental influence on children's eating. The subjects responded to a self-reported questionnaire. Excluding the incomplete responses, the data (n = 3,435) were analyzed using ${\chi}^2$-test or t-test. RESULTS: The group that had more frequent family dinners (${\geq}$ 5 days/week, 63.4%), compared to those that had less (${\leq}$ 4 days/week, 36.6%), showed better eating habits, such as eating meals regularly, performing desirable behaviors during meals, having breakfast frequently, having breakfast with family members (P < 0.001), and not eating only what he or she likes (P < 0.05). Those who had more frequent family dinners also consumed healthy foods with more frequency, including protein foods, dairy products, grains, vegetables, seaweeds (P < 0.001), and fruits (P < 0.01). However, unhealthy eating behaviors (e.g., eating fatty foods, salty foods, sweets, etc.) were not significantly different by the frequency of family dinners. CONCLUSIONS: Having dinner frequently with family members was associated with more desirable eating habits and with healthy eating behaviors in young children. Thus nutrition education might be planned to promote family dinners, by emphasizing the benefits of having family meals on children's health and nutrition and making more opportunities for family meals.

Objectives: To evaluate the critical environmental factors on healthy-aging of Korean people, we investigated the significant factors influencing health status of septuagenarians living in rural area of Jeonla province, known to be one of the representative longevity regions in Korea. Methods: We divided subjects into healthy group (36M/25F) or poor-health group (26M/73F) based on self-reported health status, body mass index, a number of prescription, and blood test data. General characteristics, physical measurements, lifestyle, dietary behavior and nutrient intake, physical health and mental health data were statistically compared between the two groups. Results: Average age was not different between healthy group and poor-health group in men and women, respectively. In men, significantly favorable factors to health were observed to be higher education, regular exercise, higher grip strength and walking function, body mass index (${\geq}18.5kg/m^2$), moderate frequency of drinking and eating-out, non-smoking, normal red blood cell (RBC) count, higher serum dehydroepiandrosterone-sulfate (DHEAS) level, good digestive function and appetite, normal hearing function, regular meals, adequate vegetable and fruit intake, diverse food intake, adequate energy and nutrients (protein, vitamin $B_1$, $B_6$, C and E, folate, niacin, P, Zn and K) intake, higher mini-nutrient status assessment (MNA) score and low level of depression. On the other hand, in women, those were literacy, living arrangement, moderate frequency of drinking, healthy teeth, higher grip strength and walking function, bone mineral density, normal RBC and white blood cell (WBC) count, higher DHEAS concentration, higher MNA score, normal cognition and memory function, having snack and adequate fruit intake. Conclusions: These results could be useful to plan effective strategies to increase health-life expectancy of Korean old people living in rural areas.

Zinc is an antioxidant trace mineral, scavenging free radicals and known to be involved in inflammatory reactions. The prevalence of atherogenic diseases such as coronary heart disease (CHD) are increasing in Korean adults of middle age and elderly. The increased cell damage from free radicals and inflammation have been implicated in etiology of CHD, and the evidence is accumulating that low zinc status is involved in the prevalence of this inflammatory atherogenic disease. However, little is known about the zinc status of Korean CHD and its relationship with dietary zinc intake and zinc bioavailabilty. In this study the serum zinc levels of male patients with CHD over 40 yrs. were compared with that of healthy adult males and its associations with dietary zinc intake and zinc bioavailabilty affecting factors were examined. Serum zinc level was measured by HANARO research reactor using neutron activation analysis (NAA) method. The overall proportion of patients with zinc deficiency, serum zinc concentrations below $74.0{\mu}g/dL$ was 32.8% compared to the 10.3% in healthy group. The average serum zinc levels were $80.7{\mu}g/dL\;and\;88.3{\mu}g/dL$ in patients and healthy group, respectively, showing significantly low zinc status in CHD patients compared to healthy group. The intake of nutrients such as energy, carbohydrate, iron, and copper of CHD patients was significantly higher compared to that of the healthy group. In addition, the intake of calcium, iron, and protein from vegetable foods was significantly higher in CHD patients than that of healthy group. The dietary zinc intake was $12.7{\pm}4.5mg$ and $11.5{\pm}6.9mg$ in CHD patients and control group, respectively, which showed no difference. The phytate intake of patients group, which is 1389.0 mg, was significantly higher than the control group which showed 1104.8 mg. However, the ratio of phytate: zinc or phytate * calcium. zinc per 1000 kcal energy intake did not show any difference between two groups. The serum zinc levels did not show any correlation with zinc or factors that affect the bioavailability of zinc. The dietary factors influencing the zinc status were not found in CHD patients.

Health Belief Model is a socio-psychological theory of decision making to individual health-related behaviors. This study was aimed to develop an effective education program for hypertension based on health belief model. The main factors of health belief model were investigated by focus group interview (FGI) with 23 hypertensive or prehypertensive subjects aged over fifty years. 'Perceived susceptibility' to hypertension was family history, neglect of health care, preference for salty food, broth of soup and stew. Lifelong medication, complications, and medical costs were reported as 'perceived severity' of hypertension. 'Perceived benefits' of hypertension management were decrease of medicinal dose, reduction of medical costs, and healthy eating habits of the family, while 'perceived barriers' were lack of palatability of low salt diet, convenience-oriented dietary habits, and limited choice of foods when eating out. Subjects mentioned TV health programs, public health center programs, and advice from doctors and family as 'cues to action' of hypertension management. These qualitative information provided basis for developing a nutrition education program for hypertension which could be implemented in the public health center. Eight week program was composed of understanding hypertension, risk factor management (eating habits, weight), low salt diet (principles, cooking), advanced management for healthy diet in 2 sessions, and summary. Each session was designed to alert the susceptibility and severity, to emphasize the benefits, and to reduce the barriers by providing dietary monitoring, practical advice, and action tips.
